GRAINeSAVING DEVIGE FOR PNEUMATIC STACKERS.

Specification of Letters Patent.

Eatent'edNov. 19,1901! Application filed January 9. 1907- Ssrial No. 135L617.

To all whom it may concern:

Be it known that I, J OSEPH a citizen of the United States, residing at Dresden, in the county of Decatur, State of Kansas, have invented certain new and useful Improvements in Grain-Savin Devices for' Pneumatic Stackers; and I 0 hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

, This invention relates to grain saving devices for pneumatic stackers, and more par ticularly to that class which consist in placing, in the stacker tube one or more screens through which loose grain may be screened from the straw passing through the tube and deposited in a suitable collecting trough arran ed upon the under side of the tube.

it y invention resides primarily in the pro-- vision of a novel form of screening element which,'whi1e it will efiectually perform its function, will not clog the tube, a disadvantage'found in most of the devices of this class now on the market. In carrying out my invention I form in the stacker 'tube one or more openings and securedv within the tube and rearwardly of the openings, a number of upstanding fingers which project forwal dly over the openings, it being under- Y stood'uthat the straw is blown over these screens, thus formed, and that the grain which has accidentallybeen carried into the stacker tube by the straw, is screened and falls through the openings and into a trough arranged upon the under side''- of the tube, which trough leads to the return conveyer.

In the accompanying drawings: Figure 1 is a side elevation of the invention, Fi 2 is a detail vertical "longitudinal sections. view therethrough, Fig. 3 is a detail horizontal sectional view, Fig. 4 a detail'vertical transverse sectional view taken in a line with one of the openings through which the grain drops, and, Fig: 5 is a view similar to Fig. 4

buttaken at a point where the stacker tube and the trough are telescoped.

- Referring more specifically to the draw-f ings, the numeral 5 denotes the fan casing of the-stacker and 6 the stacker tube which leads from the an casing. This stacker tube is preferably formed in sections which;

telescope and to this end 'onc or more movable sections 7 are provided. While it is to W. NIATOUSEKL be understood that an number of these sec- ,tlOIlS may be employe I only show one and illustratethis as being connected with the stacker tube proper 6. The section 7, at its. end which is designed for connection withthe fixed section 6, ,is enlarged as at 8 so asto telescopically receive the outer end of the said fixed section. Y

In the under side of the.fixed-se'ction 6, there is formed an opening 9 and a similaropening 10 is formed in the under side of the 'movab e section 7 and secured at their rear ends by riveting or. otherwise as indicated at 11', to the inner side of the stacker tube sections and adjacent the rear edges of the openin s 9 and 10 are fingers 12 which are bent a jacent their rear ends so, as to extend slightly upwardly and forwardly above the openings and slightly beyond the for-' ward edge thereof t us forming a grate over the openings. These fingers are formed of resilient metal and are to a slight degree yieldable so that passage of the straw over the fingers will not be interrupted thereby and to further avoid this interruption of the straw, the extreme forward ends of the fingers are curved downwardly as at 13. From the above described construction it will,,be observed that any loose grain which malg have been carried by the straw into t stacker tube, will be screened by the fingers and willfall through the openings 9 and 10-;

.In order to-collect the grain which is discharged through the opemngs in the stacker tube, as above described, I have provideda suitable trou h which, as in too case of the stacker tube,1sfonnedin telesco ic sections, these sections being indicated by t e numerals 14 and 15. The trough section 14 is secured at its u per' edges to o posite sides of the fixed tu' e section fi an the trough section 15 is secured in a similar mannerto the movable tube section 7. The rear end portion of the'trough section 15 isenlargedas at 1.6 to permit of the telescopic reception of the trough section 14, the upper edges of the en.- larged portion of this trough section being free from the tube section 7 so that the telescopic movement of the sections'may be spect to the blower, the othersection bein ,IO

end secured to the tube section 7.

secured at its upper edges to opposite sides behedth the said section, the forward portion section secured througlunit the entire length chine (not shown). The forward end of the I trough section. 15 is bent upwardly as at 19 What is claimed. is:- 4

A neumatics-backer comprising a, blower, a stacker tube'lending from the blower and comprised ofs pair of stacker tube sections, one of the said sections being iixe(l;with retcleseopically engaged over the outer cm of the said. fixed section, a trough section of the fixed section and thereby positioned of the said tnction being spaced at its upper edges is spect to the irxefl stacker tiihe section to which it 18 secured, it trough of its Upper edges to the movable stacker I tube section and. tlierehy positioned beheath the some, the trough section upon the i forward end, a spout leading from the said troughseotion at its rear end, the forward end ofthe trough section upon the movable stacker tube section being closed and the said trough section being telescopically received in the trough section upon'the fixed stacker tube section, the two tube sections being provided each with an opening, find fingers secured at their ends Within the tube adja cent the rear edges of the corresponding openings, said fingers being extended forwardly in an inclined plane above the said respective openings and having their forward ends turned downwardly.

In testimony wl-icreof, I aflix my signature, in presence of two Witnesses.
